Heat Recovery • Pinch Studies—Methodical way

to get heat & use where most needed

• CHP—combine electricity generation with use of waste steam for heating

• Heat Pumps—pull heat from wastewater, use in steam production

• Reuse Wet End Hot Water

Reduce Fuel Costs

• Fuel Conversion – Biomass – Wastewater sludge – Tire Derived Fuel – Natural Gas

• Arbitrage (Fuel Switching) – Biomass/Purchased

Electricity – Natural Gas/Oil
